Unix Tip #4616- October 31, 2025
USES FOR AWK
If you have a server
with alot of filesystems
on it (oracle/SAP
environments) then this
little awk command can
come in useful. It can
obviously be used in many
other situations also. In
this example, the file
structure is /oracle/PRD/xxxx.
awk '/PRD/{ print "umount " $3 }' /etc/vfstab | /sbin/sh
If you run it without
piping it to 'sh', then it
will show you what the command
will do. You can replace the
'umount' with whatever command you
like. It's a quick and easy though.
NOTE: All tips provided are USE AT YOUR OWN RISK. Tips are submitted
